Optical coupler/splitter
A device that couples or splits power from fiber optic cables.
Photocurrent
The current that flows through a photosensitive device as the result of
exposure to radiant power.
Photodiode
An electro-optic component that converts optical energy to electrical current.
PMF
Polarization maintaining fiber-fiber optic cable with a core that has been
pre-stressed to create two independent optical axes. Light is transmitted
through these two optical axes without exchanging energy with each other.
PRBS
Pseudo-random binary-pulse sequence. A repeating bit pattern that appears
to be random. The bit pattern is used for telecommunications system testing.
Protocol
Formal conventions that govern the format and control of signals in a
communication process.
Pulse modulation
The modulation of a series of pulses to represent the information.
Random jitter
Abrupt, spurious variations in the timing or amplitude of a signal, whose
value at a future instant cannot be predicted.
Recovered Clock
A clock signal derived from and synchronous with a received data sequence.
Refraction
The bending of light as it passes between materials having different
refractive indices.
Residual Error Rate
The error rate remaining after attempts at correction are made.
RZ
Return to Zero-When a digital data pattern that has zeroes as lows and ones
as highs, returns to zero when the pattern has consecutive ones.
Rx
An abbreviation for receiver.
Short wavelength
The spectrum from 800 to 1000 nanometers.
